The oxidation state 5 can be produced by dissolving manganese dioxide in molten sodium nitrite.
When you select an oxidation state an arrow points to the petri dish containing an aqueous solution of a compound in this oxidation state appropriately colored. Electron configuration of manganese is ar 3d5 4s2. In its compounds manganese exhibits oxidation states from 2 to 7. The common oxidation states are 2 4 and 7 but the less common 3 5 and 6 states are easily prepared.
